Re: Bytek Fireman 8x

Yes, Cameron, the 2532 does go to FFFh, a 2716 fills to 7FFh.

If you have a logic probe with a 'memory' you can use that on a read
to see if the A11 toggles. You can use a voltmeter as well...Pin 12
is Gnd, I would stuff thin wires into the two socket opening and clip
the voltmeter to them.

If it toggles on a read (it will start Low, then go High at 800h) but
not on write (write FFs that you just 'read') then you have more
information.
